Okay, so a little over a week ago my first betta Kevin died. I had him in quarantine, heated and being treated for ich with Kordon Rid-Ich Plus treatment when he passed away. I got my new betta Luke last Thursday, and he's having the same problems, but I'm not so sure that its ich. I'll give you the most info I can:
Aqueon 5-gallon, cycled. Heated to about 78 F and filtered. Plenty of plants and hideouts. Using API Betta water conditioner and API quick start. Excellent water params.
Since he's so small, I crush up one micro pellet a day, and give him a chopped up freeze-dried bloodworm several times a week.
Type of betta:
Dragon scale crown tail, really young. His body is maybe between 1/2 inch to 1 inch in length. Bought at Petsmart.
: Like Kevin, the scales around his face have turned white/tan-ish, and he's spending a lot of time around the bottom of the tank, which is out of character for him. He's a bit clamped as of now, and seems a bit more energetic after his 50% water change. Appears to have some fin rot with either white regrowth or... not sure if this is also a symptom, but the tips of his rays are white. I also noticed he seems to have some white flecks on each eye and his scales around his face are slightly protruding/pineconing. Looks like some are missing, possibly lesions? I'm not sure what those look like tho.
Also, his filter material seems to be slightly greenish instead of the white I bought it as. Pretty sure its algae but I don't want to leave anything out.
Dosing with Bettafix (trying to stay slightly under the recommended dosing, as I've heard of problems with it). Upped water changes from 25% weekly to 50% every other day.
I'm fairly sure that its columnaris at this point, but I'm still a newbie. After Kevin died, I sanitized the tank to the best of my abilities and cranked up the temp to the low 90s while there were no fishy inhabitants. Let it sit for about four or five days with a carbon filter going to get rid of all the nastiness before I went out and bought Luke. But reading the description of columnaris, it seems like cranking up the temperature was probably the worst thing I could have done. :( Help! I don't know what to do! If anyone could prescribe some cheaper medications to heal him that would be great!
